OILING ATTACHMENT.

Specification of Letters Batent.

Patented Sept. 1, 1908.

To all whom it may concern:

Be it known that I, LAVALETTE L. LOGAN, a citizen of the United States, residing at New Haven, in the county of Fayette and State of Pennsylvania, have invented new and useful Improvements in Oiling Attachments, of which the following is a specification.

This invention relates to a disk oiler attachment for car axles and journals, and is particularly adapted for use in connection with mine cars.

The present oiler attachment is an improvement of the structure "disclosed by my Patent 801,731, dated October 10, 1905, and essentially comprises means for frictionally connecting the disk or oil elevating means to the car axle by frictional engagement with the latter.

In my patented construction the disk was removably attached to the axle by a pin passing through the said. parts, openings being formed both in the disk and axle to receive the pin. The opening in the axle weakened the structure of the latter, and furthermore the pin was liable to shear by a side motion of the car. A still further disadvantage in the patented construction using the pin was that when water would get into the bearing and freeze the axle would not turn. It frequently happens that water does et into the bearings of mine cars, particularly in wet mines, or when the cars are permitted to stand outside over night, and during the winter season it is obvious that the Wet exposed bearings will freeze.

The present oiler attachment comprises either a disk secured to the car axle by novel means without forming an opening through the axle, or in some instances, a lifting device other than a disk removably applied to the axle to pick up the oil from the journal box, but in both structures frictional contact between the disk or lifting device and the axle is relied upon as the securing means.

In the drawings: Figure 1 illustrates a transverse vertical section through a portion of a mine car, taken in the plane of one axle and showing the improved disk oiler applied thereto. Fig. 2 is an end elevation ofthe journal box. Fig. 3 is a top, plan view of the box. Fig. 4 is a detail elevation of the disk oiler and frictional securing device therefor.

Fig. 5 is a transverse vertical section through the disk oilerand axle, and showing the frictional securing device in operative position in relation thereto. Fig. 6 is a longitudinal vertical section showing a portion of the axle and the disk oiler in section. Fig. 7 is a cross-sectional view of the axle showing the frictional oil lifting device used alone. Fig. 8 is a longitudinal vertical section of the journal box adapted for use with the oil elevating device without the disk.

Similar characters of reference are employed to indicate corresponding parts in the several views.

The numeral 1 designates a mine car body having a bottom frame 2 which may be 'of any suitable form for the reception and connection of a rotatable axle 3. One wheel 4 is preferably rigidly secured to the axle and the other wheel 5 runs loose on the axle. It is the object of this arrangement to have the wheels run independently of each other so that cars, particularly mine cars, can round short curves more readily, and in the event that boxes are set on the bed or truck frame of the car in slightly irregular position or askew they will be forced to wear and fit neatly, and at all times the axle must turn and insure lubrication with very little turning of the loose wheel thereon, and thus wear of the wheel hubs is reduced to a minimum and wabbling of the wheels prevented.

The essential feature of the improvement, as before indlcated, consists of a disk havlng ano ening 7, the upper and wider part of which has a cross-web 8 extending thereacross to strengthen the disk structure, the center of the opening 7 being materially greater in diameter than the diameter of the axle, the said upper wider portion of the opening being outwardly flared, as shown by Fig. 5. In this form of the attachment a spring yoke 9 is used to secure the disk to the axle, the legs 10 of the yoke being shaped to closely hug or embrace the axle, the yoke being removably inserted through the upper portion of the opening 7 intersected by the web 8. The upper portion or head 11 of the yoke is Wider than the remaining portion thereof and snugly fitsin the upper flared portion of said opening 7, and by this means the yoke is maintained in operative relation and the legs 10 permitted to have ample exable proportions and contour and having uppansion when the axle is inserted therebej tween, as will be hereinafter referred to. This yoke 9 is formed from spring band metal of suitable width and the head 11 is given an arcuate contour so that when it is a plied the outer surface of the said head will coincide with the erimeter of the disk. The yoke 9 frictional y locks or secures the disk 6 to the axle 3 and is disposed in the opening 7 of the disk prior to the application of the axle in a manner which will be presently explained.

The disk oiler attachment just described is used in a journal box or receptacle 12 of suitper horizontally disposed securing flanges 13 which are adapted to be bolted or otherwise secured to a truck frame or the end or bottom frame of the car. The fastening means employed for attaching the receptacle will be of such nature that they can be readily removed. The chamber 14 of the receptacle has bearings 15 projecting centrally thereinto from opposite sides, and leading to the said chamber is a filling channel 16 accessible through one of the flanges and normally closed by a suitable cover which may be similar to that disclosed in my patent hereinbe fore mentioned. The top of the receptacle. is open as at 17 and surrounded by an extension or vertical flange 18 which is adapted to be projected into a recess or seat 19 on the un der side of the truck frame or bottom framework of the car, as shown by Fig. 1, and when the receptacle has thus been applied and secured in place the chamber 14 will be closed, and dust, dirt, or grit excluded therefrom, and by the provision of this extension or ver tical flange movement of the receptacle on the truck frame or body framework or bed of the car is also prevented.

The disk 6 with the yoke 9 inserted therein is placed in position in the chamber 14 of the receptacle 12 and the axle is inserted endwise through the bearings 15, the center of the disk 6 and between the legs 10 of the yoke, the o posite extremities of the axle being reduce as shown for this urpose. When the axle is pushed through t e disk between the legs of the yoke, the disk becomes frictionally connected to the axle through the medium of the yoke and at any time desired or found necessary the yoke may be detached by drawing the same upwardly through the opening 17 of the receptacle or journal box when the axle and journal box are disconnected from the car body, and the separation may be readily completed by pulling the axle out of the journal box and the disk. The axle is free to slip longitudinally between the legs 10 of the yoke, and any sidewise movement of the car will thus be compensated for without injury to the oiler attachment or axle. It will be understood that a quantity of oil is placed in the rece tacle 12 and as the axle rotates the disk 6 pic s up the oil and carries it over the axle to a oint whence it runs down the sides of the disk to the axle and continually lubricates the latter. In the event that water gets into the receptacle 12 and freezes about the parts of the attachment, the axle will be free to turn within the yoke legs and movement of the car can be effected until the parts of the attachment thaw out. The opening 7 at the center of the disk, being of greater diameter than the combined diametrical extent of the axle and the legs 10 of the yoke, permits the said yoke legs to expand sufliciently to accommodate the application of the axle.

From the foregoing it will be seen that the disk 6 operates-as a pick-up means and is separably and frictionally connected to the axle, the oil or lubricant elevated by the disk being not only fed to the axle but also to the bearings 15.

In Figs. 7 and 8 the oiling attachment is shown in simplified form, and therein the yoke 9 is used in connection with the axle 3 without the disk 6, the bearings 15 of the receptacle 12 having in this use of the attachment their inner ends in closer relation. In this variation in the use of the attachment, the yoke may be readily inserted through and withdrawn from the rece tacle at the top, the opening 17 being use for this purpose. The yoke 9 when used alone with the axle will effectively lift the oil from the receptacle chamber as in the use of the disk, and, furthermore, the yoke rotates regularly with the axle and is frictionally connected to or held on the latter.

The improved oiling attachment will be found exceptionally convenient in its application and operation as well as economical in the use of oil or other lubricant.

It will be understood that changes'in the proportions, dimensions, and minor details may be resorted to without departing from the spirit of the invention.

Having thus described the invention, what is claimed as new, is:

1. An oiling attachment comprising a re ceptacle having an annular space to contain a lubricant, a revoluble axle mounted in said receptacle, and a spring yoke detachably positioned within said annular space and frictionally engaging and rotatable with said axle whereby the lubricant is distributed to the latter, the axle being slidable in the direction of its length in the receptacle to compensate for the necessary movement in turning curves, and also slidable through the yoke without displacing the latter from operative position.

2. An oiling attachment comprising an oil supply means, a rotatable axle, a'disk with an opening therethrough, and a resilient yoke inserted in the disk and engaging the axle to cause the disk to rotate with the latter.
